The following statement is correct: () A. The remarkable function of infrared ray is chemical action, and the remarkable function of ultraviolet ray is thermal action B. Advanced camera lens stage

A, the obvious effect of infrared ray is thermal effect, and the obvious effect of ultraviolet ray is chemical effect, so A is wrong;

B. The light irradiated on both sides of the film is reflected back. Due to the optical path difference, the vibration of the two reflected lights is weakened at the superposition place, which cancels each other and enhances the light transmission ability; The lens surface of an advanced camera is coated with an antireflection film by the interference of light, so B is correct;

C, the key component of photoelectric sensor is photoelectric tube, which uses photoelectric effect to convert light phenomenon into electric phenomenon, so C is wrong;

D. the reflected light is polarized light. Photographers often install polarizing filters in front of the camera lens to make the scene clearer. It uses the polarization of light, so d is correct;

So choose BD.
